Sherdog.com learned of the matchup Wednesday from a source close to
the bout. Despite an initial report that Carvalho was a replacement
for Mackens
Semerzier, a source informs Sherdog.com that the
Alcantara-Semerzier bout was never agreed upon.

Fighting out of Belem, Brazil, Alcantara rides an 11-fight win
streak into his UFC, and featherweight, debut. “Marajo” made his
first and only appearance under the Zuffa banner in December at WEC
53, where he out Ricardo
Lamas in the first round. Jungle Fight’s inaugural lightweight
champion, Alcantara has finished all but two of his 24 career
victims.

Carvalho, 32, will also make his Octagon debut at the event. The
Canadian has won each of his last three contests, most recently
outpointing Doug Evans on
June 10 at the Score Fighting Series. “Pato” is a veteran of TKO
and Shooto competition and holds notable wins over Hatsu Hioki,
“Lion”
Takeshi Inoue and Rumina
Sato.
